The idea of collecting the energy of the Sun in space and beaming it back to Earth to feed the electric power grid has been around almost as long as spaceflight. Now engineers in the U.S., Europe, Japan and China are developing new technologies that could make it happen. They also are devising stepwise approaches that could lower the high economic hurdles to full-scale space solar power by using those technologies to fuel lucrative advances in traditional space business, including communications satellites.
